To (LZ/ whom, zz; may concern:

Be it known that I, THOMAS RoDnRIoK, a citizen of the United States,residing at Columbus, in the countyof Franklin and State of Ohio, haveinvented certain new and useful Improvements in HeatingStoves; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates more particularly to that class of heating-stovesin which gas, natural or artificial, is the fuel; and the aim of theinvention is to provide an improved stove of this sort that shall be ofeconomical and simple construction and yet yield large results.

A heating-stove is obviously effective in proportion to the area ofsurface it presents against which the air to be heated can im pinge andbe rapidly diffused. There is no difficulty in securing an abundance ofsurface where expense is not much of a consideration; but it has taxedthe ingenuity of inventors and manufacturers to obtain a construction inwhich there is large air heating or radiating surface, small cnbicalcontent, and at the same time simplicity and economy of construction, soas to bring the stove within the reach of persons of small or ordinarymeans.

In the accompanying drawings, in which I have shown embodiments of myimprovements, Figure l is an end View. Fig. 2 is a central verticalsectional view taken on a plane indicated by the line :n Fig. 3. Fig. 3is a horizontal sectional View taken on a plane indicated by the line yy, Fig. 2. Fig. a is a side and sectional view of the upper part of thestove only, showing attachments that can be applied for cookingpurposes. Fig. 5 is a top plan View of what is shown in Fig. 4,v the endbeing broken out and shown in section.

Like characters of reference in the several views designatecorresponding parts.

Referring to Figs. l, 2, and 3, the character l designates the front, 2the back, l the top, and 3 the ends or sides, of the stove. The front isclosed over its entire area except for a suitable small opening belowthe burner, like that indicated at l, as usual in stoves of this kindand as well understood, to admit air to support combustion, and the backis likewise closed except fora suitable opening in its lower portion forthe escape of the products of combustion. The closed top 4 joins thefront and back. The front. can be snitably ornamented and provided withmica lights to render visible the gas-llame. The sides or ends 3 aremade with long large openings, the edges of which are approximatelyparallel to the general direction of the front, top, back, and bottom ofthe stove, and such openings are of the form of the cross'section of thehollow prism 6, hereinafter described. Extending between and secured tothe ends or sides 3 is a hollow prism G, of sheet metal, completely openfrom end to end and having its edges at the ends uniting with the edgesof the openings in the ends 3. This prism constitutes an air-heatingchamber, and the front side or wall thereof is only slightly inclined tocut the vertical plane passing through the burner, and the lower portionof this slightly-inclined front wall is furnished with a facing ofasbestos to protect the metal against the intense heat of the fiame.

The upper end, as well as the vertical sides, of the aiihheating chamberis solid or closed, while the lower end is perforated, as seen at Gn.

Below the airheating chamber is what might be termed a cold or fresh airchamber 7, that is separated from the burnerchamber by a verticalpartition 8 and a horizontal partition 9. This coldair chamber ispreferably provided with two collared openings, one of which is shown tohave a removable c-ap and the other with a pipe for taking air. The airto be heated can be taken either from the room in which the stove islocated or from the exterior of that room. If a valve is put in theoutdoor air-pipe, the air can first be taken from outdoors only and thenfrom the room only, orit can be taken continuously from outdoors and thesupply regulated.

Referring now to Figs. 4 and 5, in which I show how attachments can beapplied to my stove to permit cooking, lO designates an opening that canbe covered with a removable cap. ll is a damper for retarding the draftwhen increased heat for cooking or ediblewarming purposes is desired atthe top of the stove. To form an oven, parallel channels IOO or ways 12to receive sliding doors 13 are sen cured to the ends of the stoveadjacent the upper ends of the air-heating chamber, and a shelf 14 issupported on horizontal ledges 14a, secured along the inner sides of thechamber. The shelf and the doors are only to be temporarily applied andcan be taken out When the heater is to' be used forits primary purpose.With these cooking attachments the stove will be especially acceptableto those.v who from necessity or choice reside in one or a` few rooms.will be observed that the matter of putting in the heating-drum not onlysimplifies the work of construction and eects a saving in the materialemployed, but also secures large increase in the air-heating surface andpermits a rapid exit and diffusion of the air heat` ed within the drum.

-I do not herein claim the above-described attachments permitting thecooking or warm ing of foods, but have sim ply illustrated them for thepurpose of showing a use to which my construction of heating-stove canbe very easily put if these attachments be used. vWhat I claim, anddesire to secure by Let;- tersv Patent, is

lLjlna heating-stove, the front and back Aside from this, however, it'

walls substantially parallel to each other, a top, and ends or sides,large openings in said sides or ends conformingr in shape to the generalcontour of the edges of the ends', and a horizontally-arrangedair-heating ch amber of prismatic form free and open from end lto endwith the edges of its ends uniting with the edges of the openings in theends 0r sides of the stove, substantially as shown.

In a heating-stove, the front and back Awalls, the top, and the sidesor ends, large openings in said ends or sides conforming in shape to thegeneral contour of the edges of the said sides or ends, ahorizontally-arranged air-heating chamber of prism-atie form free andopen from end to end with the edges atv
